I must admit, While my Wife and I were white on white swinging , I never once worried about Her having feelings for any of Her many partners, like myself, I never found any emotional attachment to any of my female partners.
However after my Wife discovered the joys of fucking, what I would consider huge black cocks,She by Her own admission, stated She absolutely loved being fucked by them, and the bigger the better.
When She found a regular black boyfriend some 18/19 years younger than Her (@ 48/49).
She started what turned out to be a nearly 10 year relationship with Him.
She also stated to me ( When we had sex mostly) how much She adored sex with Him.
As 2/3 years went by, I felt or noticed a change in the way She spoke about Him, and felt that She was obviously having strong feelings for Him.
Fortunately for me, He was married and the ******* of two girls and although He loved fucking my Wife on His own and with various male and female friends, and although, He by His own admission thought a lot of my Wife, He always kept things in perspective.
My Wife however,I felt had a lot stronger feelings for Him, He was able to get Her to do almost anything for Him, and as their relationship developed and He learnt.more about the dynamics of Our Marriage,and what turned Me on,Knew what buttons to push.
As I have said earlier We have been swingers for a very long time , So I was used to Her having sex with other guys etc etc.
But I must admit I felt in a somewhat cleft stick situation, after I realised the extent of my Wife,s feelings for Her boyfriend, part of Me loved Her having sex that drove Her wild and part of Me felt ( What if She leaves me ? ).
All this was kept in check by the fact that He also had a family which He loved.
When the relationship between them ended, my Wife was I think 61/62, and Him around 40,ish.
As My Wife and I are in our mid seventies, and all this is in the distant past, I have asked my Wife occasionally if She would have left me for Him.
She has always been so Honest with me in everything during our long life together.
She said He never once asked Her to leave me, however She wanted Him to ask Her, to leave me,and live with Him.!!!
However She also said that It was always a fantasy She held, and whilst She,adored what Her relationship with Him brought to both our sex lives, and some of the slutty thing She did with Him.
That to Her our marriage was more important to Her, Thank God .
